Apart from the GUI stuff, mainframe operating systems did everything that
today's x86 OSs do. Early releases of IBM's OS/360 could run in 64KB
and offered Fortran, Cobol etc
The task time-sharing on release 12 (MVT, about 1971) was better than
that in Windows XP or Vista (that should start a few arguments).

I think you have that back-to-front - it is unstructured code with lots
of inlining which is incomprehensible.
